IRS254(0,1)(S)PbF
LED BUCK REGULATOR CONTROL IC
Description
The IRS254(0,1) are high voltage, high frequency
buck control ICs for constant LED current regulation.
They incorporate a continuous mode time-delayed
hysteretic buck regulator to directly control the
average load current, using an accurate on-chip
bandgap voltage reference.
The application is inherently protected against short
circuit conditions, with the ability to easily add open-
circuit protection. An external high-side bootstrap
circuit drives the buck switching element at high
frequencies. A low-side driver is also provided for
synchronous rectifier designs. All functions are
realized within a simple 8 pin DIP or SOIC package.
Features
200 V (IRS2540) and 600 V (IRS2541) half bridge
